Question

How to tell if a pedigree is autosomal or sexlinked?

Answer 1

If the pedigree is affected by both saxes such as man and female then it can considered as astosomal pedigree. But sex linked pedigree is affected by a single sex.

For example, X-linked recessive trait usually affects man because only man has the X chromosome.

Similarly, an unaffected couple can give birth of an affected child, but an affected couple cannot give birth to an unaffected child.

Answer 2

Autosomal-trait that is located on an autosome(non-sex chromosomes).


Sex linked-trait that is located on one of the two sex chromosomes.
